I have a download page on a subdomain (downloads.easyjob.net) and I'm tracking the "virtual page view" to the download following these instructions .

That part works fine. However, I also want to track the index page at downloads.easyjob.net and that's where I got into trouble: it gives me the same number of pageviews ass the entire site on www.easyjob.net, which is clearly not possible. Anybody knows what's going on?

Why not setup event tracking on the link to start the download instead of a virtual page view, track it as an event? Then you can run reports and see where those events came from organics, paid search, keywords, visitors etc.
